Guerlédan Lake

Cycle around Brittany's largest lake!

The largest lake in Brittany, with a surface area of 400 hectares and a length of 12 km, Lac de Guerlédan nestles in the heart of the Quénécan forest, between Mûr-de-Bretagne and the Abbaye de Bon Repos. A veritable ocean of freshwater nestled in a steep-sided valley that looks like a small mountain!

Formed by the construction of a hydroelectric dam, Lac de Guerlédan has become one of Brittany's major tourist attractions over the years, particularly for nature sports enthusiasts.

Hiking, mountain biking, horse riding, fishing, climbing, water-skiing, canoeing, kayaking, paddling... you'll be spoilt for choice.

And for a gentle way to explore the lake, take a guided cruise on board a speedboat.

A gigantic playground in the heart of Brittany, situated between two stages of the Vélodyssée: from Rostrenen to Mûr-de-Bretagne, and from Mûr-de-Bretagne to Pontivy!

At the heart of the Guerlédan-Argoat Country is a steep sided valley where the Blavet winds through the woods until it reaches Gouarec. The Coat Natous double lock in the middle of this stage of La Vélodyssée provides an ideal resting point.Two of the highlights of this stage are the beautiful Cistercian Abbey of Bon-Repos and Brittany’s largest lake, the magnificent Lac de Guerlédan: the perfect place to stop for a swim and sunbathe! This varied leg of the trail follows a towpath, a short stretch of coastal route and the greenway.

Designated track and very steep descent into the Guerlédan dam towards Pontivy. Here the Blavet is no longer navigable. The steep-sided valley, imposing lock keepers’ buildings and lush vegetation, give this stage of La Vélodyssée an enchanting feel.
